PHOTOGRAPHIC- PRINTING FRAME.

SPEGIFIOATION forming part of Letters Patent No. 690,131, dated December 31, 1901.

Application filed September 21,

To all whom it znay concern:

Be. it known that I, ALONZO N. OALLAWAY, a citizen of the United States, residing at San Antonio, in the'county of Bexar and State of Texas, have invented a new and useful Photographic-Printing Frame, of which the following is a specification.

My .invention relates to certain improvements in photographic-printing frames, and has for its object to constructaframe of such character as to readily permit of the raising of the glass negativefrom its printing position for the inspection of the sensitized paper and to return the same accurately to printing position.

A further object is to insure the rigid holding of the glass negative without subjecting the same to any breaking strain.

A still further object'jis to provide aframe of such construction as will permit of the spacing of the negative and the sensitized paper, sothat when desired the rays of light may be diffused and the outlines of the picture toned and softened to produce an effect similar to .that of a porcelain print.

With these and other object-sin View the invention consists in the novel construction and arrangement of parts hereinafter described, shown in the accompanying drawings, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a perspective View of a photographic-printin g frame constructed and arranged in accordance with my invention. Fig. 2 is a longitudinal sectional elevation of the same, illustrating the sensitized paper and the glass negative arranged for compact printing. Fig. 3 is a view similar to Fig. 2, showing the sensitized paper moved to a'short distance from the glass negative to permit diffusion of the light-rays. Fig. 4 is a transverse sectional elevation of the frame on the line 4 4, Fig. 2. Fig. 5 is a detail perspective view of the under side of the movable bed detached from the frame.

Similar characters of reference indicate corresponding parts throughout-the various figures of the drawings.

(N0 model.)

1 designates a fixed frame formed of suitable side and end sections rigidly secured together in rectangular form and providing an open spaceior the reception of the movable bed 2. To one end of'the frame is hinged a negative carrier comprising oppositely-disposed side pieces 3, having grooves, 4 and end pieces 5 and 6, the former being likewise slotted to receive the end of the glass negative it, while the end bar 6 is cut away to a point below the grooves to permit of the ready insertion or removal of the negative. In one or in both of the side grooves 4 are fiat springs 7, adapted to bear againstthe edge or edges of the negative and exert sufficient friction to hold the negative securely in position.

At the center of the bar 5 is secured a thumb-plate 8 for the ready manipulation of the negative-carrier when it is desired to open or close the same during the printing operation. At the extreme end of the" carrier the, side bars 3 are extended to form stops 9, adapted to abut against inclined shoulders 10, formed at the end of the main frame to prevent excessive opening movement. Between the frame and thenegativesist in moving the carrier to the open posisockets arranged in the end bar of the main frame and extending for a distance sufficient to impinge upon the plate-carrier.

The bed 2 is of such dimensions as to fit loosely within the open space formed by the bars of the main frame, and it is confined in position by spring-pressed rods 12, carrying with the inner sides of the frame, the rods being pressed with sufficient force to hold the bed in position under stress of the springs 14:, which look the negative-carrier in place, but permitting of the adjustment of the bed to a greater or less distance from the negative during the printing operation. The upper surtion, said spring being preferably inserted in I 8o face of the bed is covered, as usual, with felt or similar material 15,-forminga yieldingback adapted to receive the sensitized paper 16, l the paper being cut into proper-size and of carrier small springs 11 are employed to as- I enlarged heads 13 for frictional engagement until the printing is nearlyfinished.

sufiicient length to extend beyond the ends of the bed and be there locked in position by the pivoted locking-loops 17. On the under side of the main frame are secured longitudinal bars or strips 20, which project inwardly from the sides of the frame and form supports for compression-springs 2l,adapted to sockets 22 in the bed 2, the springs acting to keep the bed in an elevated position, but excessive movement being prevented by stop-plates 24, secured to the upper sides of the main frame.

When the various parts are assembled, the

negative-carrier is held against the strips 24 by suitable spring-fingers 14, secured to the sides of the main frame and having bearingfulcrums 25, which tend to keep them more firmly seated in locking position. These fingers can be readily moved to engage with the upper surface of the plate-carrier an d will insure good contact with the glass negative and the sensitized paper during contact. I To the under side of the bed-plate are secured bracing-strips 27, extending longitudinally of the bed and serving partly as guides for levers or arms 28, as shown more clearly in Fig. 5. The levers or arms in the present instance are adapted to transverse grooves or recesses 29 in the rear of the bed and provided midway of their length with outwardlybent portions forming loops, which may be engaged by the hand to operate the levers. The upwardly-bent ends of the levers are adapted to engage with the under side of the strips 24, and the latter for this purpose may be provided with metallic protecting-strips 31 to receive the thrust of the levers when the latter are operated.

The levers 28 serve to move the bed away from the negative, the extent of movement being dependent upon the result to be attained. To gain a porcelain effect, printing proceeds in the usual manner, with the negative in close contact with the sensitized paper The levers are then operated to move the bed and the paper a slight distance from the negative, the light-rays being then diffused and producing a softer and more pleasing effect than is possible by continuous-contact printing. The bed is held in any position to which it may be adjusted by the contact of the friction-rods 12 with the inner surface of the main frame.

Various changes in the form and proportions of the device may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus described myinvention, what I claim is- 1.
